Now let's take a look at a Warp Stabilizer shot in which the Subspace Warp option is a necessity, but it also causes too much distortion. This shot contains heavy parallax and strong rolling shutter artifacts. Rolling shutter is a particularly nasty artifact. It comes from cameras that have a CMOS chip and that chip scans from the top to the bottom frame instead of taking the entire image simultaneously. So camera such as the RED camera, any DSLR, or even the iPhone, will show this artifact.

Let me just preview this shot so we can see what we're dealing with. So we have a couple of different challenges here. Any shot with heavy left to right motion taken with a CMOS sensor is going to have rolling shutter problems of some degree. This particular shot was taken with a Canon 7D and so we know that's a factor here. But there are other issues with this shot as well.
